2. Description of the Related Art Conventionally, as shown in FIG. 7, when attaching or detaching an air filter of an indoor unit of an air conditioner, a front panel 22 is attached to the front surface of an indoor unit main body 21 attached to a wall surface. An openable front grille 23 is attached to the front of the air filter 2 and an insertable air filter 24 is provided on the rear surface of the front grille 23.
It is a general structure that the 4 is attached and detached.

By the way, in recent small and compact indoor units, when mounted at a higher position closer to the ceiling,
There is a problem that the front grill is inaccessible as well as the cleaning of the air filter arranged at the air intake port.Therefore, the actual situation is to clean up or attach and detach the air filter by going up to the step. Is. In addition, since a white type is often used for the appearance color in recent years, dirt on the suction port is particularly noticeable, and the frequency of cleaning not only the air filter but also the front grill is increasing.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems of the prior art. When cleaning, the front grill can be moved downward to easily attach and detach the air filter, and It is an object to provide an air conditioner in which the front grill can be easily removed and washed with water.

[0005]

In order to solve the above-mentioned problems, the first invention of the present application is to provide a slide groove extending vertically on both side surfaces, and a slide surface arranged in front of the slide groove. A front panel having a locking groove formed below the upper end of the slide groove of the slide surface, a first protrusion that slides in the slide groove at the upper ends of both inner surfaces, and the slide surface. The front grill has a second protrusion that slides and is locked in the locking groove, and an air filter that is attached and detached from a lower end of the front grill. The projection is loosely fitted, the second projection is brought into contact with the slide surface, the front grill is moved upward, and the second projection is locked in the locking groove, whereby the front grill is moved to the front. Attach it to the panel,
The lower end of the front grill is pulled forward to disengage the second protrusion from the locking groove, and each protrusion slides on the slide groove and the slide surface to lower the front grill. It is characterized by A second invention of the present application relates to the first invention of the present application, wherein a curved arc surface is formed upward from an upper end of the locking groove on a concentric circle of the top dead center of the first protrusion, It is characterized in that the second protrusion of the front grill is separated from the locking groove. A third invention of the present application relates to the first invention of the present application, wherein a locking hole is formed at the center of the upper end of the front panel, and a locking claw for locking the locking hole is formed at the center of the upper portion of the front grill. The front grill is locked to the front panel.
A fourth invention of the present application relates to the first invention of the present application, wherein spring pieces are formed on both sides of the front panel, while recesses for engaging with the spring pieces are formed on inner surfaces of both sides of the front grill. The front grill is locked.

[0006]

According to the above construction, when the front grill is bent and the projection is fitted in the slide groove, and the projection is fitted in the locking groove by moving along the slide groove to the top dead center, the edge of the locking hole is formed. The locking claws are locked to, and the spring pieces urge the concave portions on both sides of the front grill to fix the front grill to the front panel. And when attaching and detaching the air filter and cleaning the front grill,
By pulling the lower end of the front grille forward to remove the protrusion from the locking groove and moving it downward along the slide groove and slide surface, the air filter can be easily attached and detached, and in this state the front grille can be easily cleaned. Also, when the front grill is bent to remove the protrusion from the slide groove, the front grill is detached from the front panel, so that the front grill can be washed with water.
